Hi
I'm not sure if this is the best place to post, but you guys do seem to have a wonderful depth of knowledge.
I've interfaced to Compact Flash (CF) cards before but only within a 3.3V system. From the CF spec, it states that all CF cards should work with both
5 and 3.3V supplies. Is this really true? Can I power my CF card at 5V? If I power it at 3.3V, will its IOs be 5V tolerant?Next, with CF you can use just a byte wide data access. Is this the same for a standard IDE drive?
Thanks for any comments.
